The Byakugan has many abilities, such as Farsight, also known as Telescopic Eye, as well as X-ray Vision, 360° vision, Byakugan: Genjutsu, Seeing through others' destiny, Seeing through others' thoughts, and even the space-time type Intangibility.
However, apart from the first three, Telescopic Eye, X-ray Vision, and 360° Vision, only the Byakugan held by the Otsutsuki clan can do the rest.
Ordinary members of the Hyuga clan, whether in "Shippuden" or "Boruto", or those theatrical versions, no one has ever been able to do it.
This shows that it has either a very high requirement for chakra, or a requirement for the "purity" of the Byakugan.
There are several ways to synthesize the Tenseigan, one of which requires a Byakugan with extremely high purity as a carrier.
After Toneri snatched Hanabi's eyes, he needed to go through several "fetal movements" to awaken the "Tenseigan" in his eye socket.
During the fetal movement, he once lamented that Hanabi's Byakugan had a very high purity.
"Very good, Natsu, continue to bring the Gentle Fist Technique in the future." Kiyoshi showed a satisfied smile.
This put Natsu's heart attack ease.
"Don't worry, Kiyoshi-kun." Natsu's lips parted and she uttered a sound.
"Come here."
Kiyoshi's words made Natsu lean forward.
Then, Kiyoshi transmitted chakra into Natsu's body through the ninja headband.
He had a deeper understanding of Mōryō's power, and he was constantly improving and innovating his own Dark Medical Ninjutsu.
Now, the loss of vitality required to improve the body's recovery has decreased by more than half, and there is still room for continued optimization.
Feeling that the "Caged Bird Curse Seal" in her brain had weakened a bit again, Natsu was overjoyed.
As expected... as expected, only Kiyoshi-kun could pull her out of the cage of despair.
"Alright, next, we need to further discuss the details." Kiyoshi said lightly.
After listening to these two "Gentle Fist Techniques" only once, the progress of the Trait reached 25%.
A big reason was that when he practiced Lightning Release Chakra Mode, he was already used to spewing chakra from the chakra points all over his body.
This saved Kiyoshi a lot of time in learning Gentle Fist. As for the rest, it was naturally extrapolation.
He knows a lot of ninjutsu now, and he can be regarded as knowledgeable compared to many ninjas.
For example, Naruto's main moves were Rasengan, Multiple Shadow Clone Jutsu and Sage Mode.
It seems that there are various kinds of Rasengans, but in essence they are all extensions of the basic Rasengan, either integrating new chakra nature, such as Wind Release: Rasenshuriken, or increasing the chakra input, such as Big Ball Rasengan and Ultra Big Ball Rasengan.
Simple and crude.
Many ninjas from big clans actually only master the secret ninjutsu passed down from their families for generations, and master less ninjutsu in other aspects.
Therefore, Hiruzen was so respected and revered as the "Professor".
"I...I want to wash..."
Natsu felt Kiyoshi's gaze and had already imagined what would happen.
A hint of heat quietly appeared on her face.
Such a thing was still too shameless for her, who was accustomed to feudal etiquette.
Especially before marriage.
If the clansmen knew about it, they would definitely scold her for being a slut.
"How can training be neglected?"
Kiyoshi said righteously, and gave Natsu a black belt.
Training is a top priority, and the mysteries of the Hyuga clan must be explored without wasting any time.
Natsu pursed her lips slightly, her cheeks becoming hotter.
She took the black belt. Then she tied it on her forehead.
"Go back to the room." Kiyoshi told Guren to go back to the room.
Next is an in-depth discussion.
A little guy like Guren who doesn't even know how to use chakra should focus on learning meditation.
Guren nodded ignorantly. She looked at Natsu, who was covering her eyes, and then looked at Kiyoshi, obediently returning to her room alone.
After Guren left, Kiyoshi also started walking.
Natsu heard Kiyoshi's footsteps. Step by step, she followed Kiyoshi's footsteps carefully in the dark.
She knew that she couldn't use the Byakugan's ability...
Click!
The two entered the room.
...
"What are Kiyoshi-sama and that ghost sister doing?"
Guren didn't know that the Byakugan was a Kekkei genkai, and only thought it was a ghost.
Before long, she heard some sounds, gentle and winding, like crying and sobbing.
Guren's little head suddenly understood the key.
Yes, Kiyoshi-sama specially covered the ghost's eyes. He must be performing an exorcism.
"Kiyoshi-sama is so amazing." Guren thought.
...
"There is only a little bit of a chance, it seems it will be at Kannabi Bridge." Kiyoshi closed his eyes.
He felt the slowly rising chakra limit.
Everyone's chakra reserve is actually determined from birth.
It's a pity that even the Otsutsuki clan has limited chakra.
Kaguya relied on eating the Chakra Fruit and merging with the Ten-Tails to have an extremely large amount of chakra.
The Otsutsuki are like this, not to mention others.
Throughout their lives, not many people can have even Shukaku level Chakra reserves.
"Until my eyes evolve into the Eternal Mangekyo, I can rely on pupil power to increase the amount of chakra." Kiyoshi calculated in his heart.
Going one step further, that is to awaken the "Rinnegan", and rely on the combination of Indra and Asura's respective chakras to elicit the chakra of the Six Paths.
Only in this way can the "Rinnegan" be awakened.
"Kiyoshi...Kiyoshi-kun, I'm going back first."
Kiyoshi opened his eyes and looked back.
Natsu carefully smoothed the folds on the corners of her skirt.
After a while, she looked up at Kiyoshi.
"There's a bathroom, use it if you want." Kiyoshi waved his hand.
"Yes." Natsu nodded.
After hesitating for a moment, she went into the bathroom to take a bath.
Kiyoshi sat in the room, allocating time to practice the ninjutsu he needed to learn in order.
When Natsu said goodbye and left, Kiyoshi just hummed faintly.
...
Hyuga clan.
By the time Natsu went back, it happened to be past dinner time.
